Description

Technical Field

[0001] This invention relates to the field of endometritis treatment technology, specifically a traditional Chinese medicine composition for treating endometritis in dairy cows. Background Technology

[0002] Bovine endometritis is an inflammation of the uterine lining in dairy cows after calving. It can prolong the intercalation period, reduce milk production, increase culling rates, and raise treatment costs. Common causes include birth canal injury, dystocia, abortion, uterine prolapse, vaginal prolapse, vaginitis, cervicitis, lochia retention, retained placenta, and inadequate sterilization during artificial insemination or vaginal examinations, allowing viral infections to invade the uterus. Currently, antibiotics are the primary treatment for bovine endometritis. However, due to the continuous emergence of drug-resistant strains, the efficacy of these drugs has significantly decreased, and drug residues are easily left in livestock products.

[0041] To better illustrate the technical effects of the present invention, the following experiments are conducted:

[0042] I. Diagnosis of endometritis in dairy cows: In large-scale dairy farms, dairy cows with no significant differences in age, parity, weight, and milk yield were selected. Based on clinical symptoms, number of days without pregnancy, vaginal discharge, and uterine condition upon rectal examination, a comprehensive diagnosis was made, and 50 cases of endometritis in dairy cows were diagnosed; among them, 12 cases were acute endometritis and 38 cases were chronic endometritis.

[0043] II. Grouping and Administration: The 50 dairy cows were randomly divided into 5 groups of 10 each, namely, a traditional Chinese medicine (TCM) treatment group 1, a TCM treatment group 2, a TCM treatment group 3, a chemical drug treatment group, and a pathological control group. In the TCM treatment groups 1, 2, and 3, each cow was administered the TCM composition prepared in Examples 1-3 of this invention by gavage. The composition was dissolved in warm water, and 500g was administered to each cow once daily for 7 days as one course of treatment, with two courses of treatment. The chemical drug treatment group used a commonly used treatment method in the farm, namely, dissolving 2g of oxytetracycline powder, 2g of tetracycline powder, 1g of chlortetracycline, 1 million units of penicillin, and 0.5g of streptomycin in 200ml of distilled water and injecting it into the uterus of each cow once. The pathological group was administered 500g of physiological saline once daily for 14 days.

[0044] (1) Uterine morphology analysis: At 7, 14, 21 and 28 days postpartum, the uterine morphology indicators of dairy cows in the traditional Chinese medicine treatment group 1, traditional Chinese medicine treatment group 2, traditional Chinese medicine treatment group 3, chemical drug treatment group and pathological control group were recorded in Table 1 below. The cervical longitudinal diameter and uterine horn wall thickness were measured by rectal examination.

[0045] Table 1. Analysis of Uterine Morphology

[0046]

[0047] Table 1 shows that in dairy cows with endometritis, the cervical longitudinal diameter and uterine horn wall thickness all showed a decreasing trend within 7-28 days postpartum in the traditional Chinese medicine treatment groups (Group 1, Group 2, Group 3, Group 4, and the pathological control group). However, the rate of decrease in cervical longitudinal diameter and uterine horn wall thickness was faster in the traditional Chinese medicine treatment groups (Group 1, Group 2, Group 3, and the Group 4). Among these, the rate of decrease in cervical longitudinal diameter and uterine horn wall thickness in the traditional Chinese medicine treatment groups (Group 1, Group 2, and Group 3) was similar to that in the Group 4. Therefore, it can be concluded that the traditional Chinese medicine composition prepared in this invention can promote the repair of postpartum uterine tissue in dairy cows and reduce the occurrence of endometritis.

[0048] (2) Analysis of uterine secretions: After cleaning the vulva of dairy cows in the Chinese medicine treatment group 1, Chinese medicine treatment group 2, Chinese medicine treatment group 3, chemical drug treatment group and pathological control group with disinfectant, the vulva was opened with a vulvar dilator, and a sterile cotton swab was inserted into the cervix and gently rotated to collect uterine secretions. The color, odor and viscosity of the secretions were observed and recorded in Table 2 below.

[0049] Table 2 Analysis of Uterine Secretions

[0050]

[0051]

[0052] Table 2 shows that the secretions from cows in the traditional Chinese medicine treatment groups 1, 2, and 3, and the chemical drug treatment group were all white, transparent, thin, and had a bloody smell but no foul odor. In contrast, the secretions from cows in the pathological control group were yellowish-white, cloudy, flocculent, viscous, and had an unpleasant and putrid smell. Therefore, it can be concluded that the traditional Chinese medicine composition prepared in this invention can reduce the growth of bacteria in the uterus of cows after calving and reduce the risk of bacterial infection in cows after calving.

[0053] (3) Analysis of estrus and conception: The average time to first estrus (unit: d), the time to first mating (unit: d), and the conception rate (unit: 100%) within 2 estrous cycles were tracked and recorded in dairy cows in the Chinese medicine treatment group 1, Chinese medicine treatment group 2, Chinese medicine treatment group 3, chemical drug treatment group and pathological control group after medication; and recorded in Table 3 below.

[0054] Table 3. Analysis of Estrus and Conception

[0055]

[0056] Table 3 shows that the first estrus and first mating times of dairy cows in the traditional Chinese medicine treatment groups 1, 2, and 3 and the chemical drug treatment group were similar and significantly lower than those in the pathological control group. Furthermore, the conception rate of dairy cows in the traditional Chinese medicine treatment groups 1, 2, and 3 and the chemical drug treatment group was significantly higher than that in the pathological control group. Therefore, it can be concluded that the traditional Chinese medicine composition prepared in this invention can promote rapid estrus and mating in dairy cows, while also increasing the conception rate.

[0057] (4) Blood biochemical index analysis: Blood samples were collected from dairy cows in the following groups before treatment, on day 3 during treatment, and on days 1, 7, and 15 after treatment: Traditional Chinese medicine treatment group 1, Traditional Chinese medicine treatment group 2, Traditional Chinese medicine treatment group 3, chemical drug treatment group, and pathological control group. Blood biochemical indexes were tested. The biochemical index analysis included interleukin-1 (IL-1), interleukin-2 (IL-2), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ). The unit was pg / mL. The results were recorded in Table 4 below.

[0058] Table 3. Blood Biochemical Indicators Analysis Table

[0059]

[0060]

[0061] Table 4 shows that before treatment, there were no significant differences in interleukin-1, interleukin-2, interleukin-8, tumor necrosis factor-α, and interferon-γ levels in dairy cows across the traditional Chinese medicine (TCM) treatment groups 1, 2, and 3, and the chemical drug treatment group. However, after treatment, over time, the levels of interleukin-1, interleukin-2, interleukin-8, tumor necrosis factor-α, and interferon-γ in all three groups continuously decreased. In contrast, in the pathological control group, the levels of interleukin-1, interleukin-2, interleukin-8, tumor necrosis factor-α, and interferon-γ in dairy cows continuously increased until day 15 after treatment, at which point they began to stabilize or slightly decrease. Therefore, it can be concluded that the TCM composition prepared in this invention can significantly reduce the levels of interleukin-1, interleukin-2, interleukin-8, tumor necrosis factor-α, and interferon-γ in the serum of dairy cows with postpartum metritis, thereby improving the body's immune anti-inflammatory capabilities and preventing metritis.

[0062] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
